I just install a Panisonic Deck into my acura, for some reason when I turn it on it makes a popping noise about every 3 seconds. I have no idea what could be the problem.

acura rx8?
It sounds like some kind of grounding problem that is often associated with integrating two different wiring schemes. Was the factory radio in the car? Did you use a hrns or cut the factory hrns? Was the system in the car a "premium" such as a blose or infinity?

blose?
do you think that poorly of them?

I figured out the problem with my deck .. and I wasnt paying attention when I wrote the article I didnt put it in my summer car I put it in my truck. My truck is an 84 ranger. Now however, my deck wont put out to my speakers front or rear. I am running a CQ-df200u panasonic deck. I have been told by a close friend of mine who is an installer for a local shop that this might be a common problem with the deck .. does anyone know?

lotta highs, and no lows, gotta be bose... I really don't like much of anything they do with a few exceptions. they have some descent designes, but without paul harvey they would be no where. Little bit too much snake oil in the mix and not enough performance. Their car audio sucks as well.................
Ok, I feel better..
It sounds like it could be a grounding problem. An 84 ranger could be a common ground system(one ground for 4 speakers), where all newer cars are not.
how many speaker grounds do you have on the deck?
ranger_pickup on 02/17/2004 03:44:12
There is only one ground for the whole deck. However I had a crappy Sony Xplode deck in the truck before and I never had any problems berfore ... like I said the only thing I can think of is that it is a problem with the deck. I know the speakers are connected correctly and that all the wires are in thier proper spots I have gone over it a number of times .. I am soo puzzled it isnt even funny .. ttocs your a great help and if you can keep it coming that would be sweet.

I don't mean the pwr ground, I mean the speakers ground.
There are two kinds of wiring scenarios common in cars. Common ground is the most widely used, it is easily distinguished as there is a posative and a neg(ground) for each speaker. A common ground will have a posative for each speaker, and one neg for all the speakers. Putting one wiring system in another will often lead to popping or buzzing noises. . A ford of that year could very easily have a common ground system. You can fix it if that is the case...

Can you explain the "other style ground" now used in most car installs as well ttocks. I think it is called isolated grounding or a "floating ground?"

hahaha see I really need this site ... its a common ground off the deck .. but I have used a stereo with common ground before and it never did ne thing before

that is correct, you can wire a common ground radio to a floating ground wiring system with no problems. But you cannot wire a floating ground(2 wires per) deck to a common ground wiring system. There is a good chance your truck is wired for common ground(1 ground per).
A floating ground system is easily noticed as it will have two ground per speaker. This is how most cars are wired, and how most decks are wired. So if you take the floating ground radio and wire it into the common ground vehicle(your truck) you will end up with extra speaker wires comming off of the radio. It either will not play, or more then likely sound bad. there are two things you can do to fix this. You can run a new ground wire to each speaker is typically the easiest way. The other option is to seperate the grounds. Common ground gets its name because the four ground wires will come together somewere at one common point. I have seen this be at the hrns behind the radio(makes sperating easy), or sometimes they hide them in the kick panels. In any even to seperate them you simply gut them and run wires from that point, to the radio ground wires. Damn I am up too early on my day off....

well .. I understand what your saying .. but I dont have extra speaker wires coming off the deck .. so I dont see how that could be the problem .. the deck that was in the truck before had the exact same wiring setup except it had an illumination wire where as this one does not ... I cannot figure out the problem and it is really quite frustrating.

You may have to go through a process of elimination to find this glitch.
Most newer vehicles have a floating ground system for the speakers. That means each channel output has 2 wires. A Pos and Neg wire to each speaker.
Your HU probably has:
1. A main power feed that goes to ACC/IGN wire circuit. (red is norm)
2. A black ground wire... ground this to the floor pan
3. Illumination wire can be disconnected for now, just to see if all will work noise free first
4. Constant +12 input for MEM & clock (has power when key is on or off (in fuse box usually is a tap)
5. Antenna/REM +12 volt output for power antenna or amps (this is often blue or bl/wt stripe)
6. 4 paired wires to speakers (RF,LF, RR, LR)
The only wire that can be left unconnected is the Ill wire. This wire is usually connected to the dimmer light switch and changes light output at the display when lights are on or dimmer is adjusted.
Try these basics first. Observe wire colors on the HU and know where they are supposed to go on the main wiring harness. It is often best to use an OEM/Aftermarket conversion harness as it really simplifies the wiring process a lot.
Finally, your HU grounding wire should be well grounded to floor pan... NOT OEM HARNESS !!! This means getting out some sandpaper, get to bare metal, then attach HU ground wire to that spot. A dab of silicone sealer will prevent rest and you can use a #6 x 3/4" self tapping sheet metal screw to attach grounding wire to floor pan.
Good luck,
Swez
